Digital video processing and cataloguing system and method based on cloud edition technology

Abstract

The invention discloses a digital video processing and cataloguing system and method based on a cloud edition technology. The system comprises a cloud edition client, a cloud edition service center, a cloud media processing center and a cloud storage platform, wherein the cloud edition client is communicated with the cloud edition service center through an internet; the cloud edition client comprises a cloud editor and an intelligent media stream buffer; and the cloud edition service center comprises a WMS (web media service) cloud edition media server, an ML (markup language) cloud edition material library, a cloud transmission accelerator and a CMPC (cloud media processing center). According to the digital video processing and cataloguing system and method based on the cloud edition technology, the processing and cataloguing area of digital video materials can be enlarged, and the processing range can be extended to the internet; the edition client can encrypt and buffer an acquired material stream into a memory or a local disk, so as to ensure the security of the materials; after the client edits the materials, the cloud center cluster media processing service can generate new programs, so as to ensure the concurrency between the ''cloud-client'' works; the materials need not to be downloaded to the local disk first, so that the timeliness can be enhanced; and the material stream can be collected and catalogued simultaneously.

Description

technical field [0001] The invention relates to a digital video processing and cataloging system and method based on cloud editing technology. Background technique [0002] The current digital video processing and cataloging technologies are distinguished according to the processing mode of program materials, and can be mainly divided into two types: material processing and cataloging based on local files and material processing and cataloging based on network files. [0003] The most commonly used program material processing method by TV stations and other media organizations is based on local files, which can directly access the original high-quality bit rate or proxy bit rate material, and can provide rich subtitles, special effects and other functions to meet the needs of fine editing. However, local file and material processing must be built on its own dedicated network, and each workstation must be able to directly access video material disks, resulting in strict restr...

AI Technical Summary

Problems solved by technology

[0006] 1) Each processing is automatically downloaded to the local, so that the editor can directly access the material on the local disk, the material is easy to lose, the copyright is difficult to control, and the security of the material cannot be guaranteed;

[0007] 2) Each production needs to go through the process of uploading and downloading. The entire file must be downloaded before production can start. After the file is produced, it needs to be uploaded back to the system, so the timeliness is poor;

[0008] 3) The production results can only be generated on the local machine, which takes up a lot of performance resources of the machine, which is not conducive to continuous work, and the efficiency of the production staff is greatly reduced

[0009] Generally speaking, neither of the above two video material processing and cataloging technologies can meet the online processing and cataloging needs of video authors or editors and reporters through the Internet at any time, any place, and fast response.
